This sense appears almost exclusively in fixed prepositional phrases: on camera (being filmed), off camera (not being filmed), or in front of the camera. It is not used with articles (❌ 'a camera' for this meaning). Distinguish from sense 1 — in sense 2, camera refers to the recording situation, not the physical device.
